I have just aquired a 1997 f150 and I'm trying to find a way to put an extra input in it. It has a stock factory stereo with a cassette player, but no Cd. I have heard that you can use the CD changer input but I don't know if my stereo has one. If I can do that it would be great, but if I can't what would be my next best option?

 

Buy a new one, like my Alpine 9833.

 

Is that my only option? I was hoping I wouldn't have to invest that much just to get an input.
